Abstract
Abstract The formation of a complex surface on a workpiece in which a workpiece and a tool having a contour providing an operative cutting surface substantially complementary to the desired surface to be formed are supported in overlapping relationship and the tool and workpiece are subjected to a relative translational forming movement along a closed trajectory line in a plane perpendicular to the direction of feeding movement so that any point on the operative cutting surface of the tool follows an identical trajectory to progressively engage points on the operative movement along a closed trajectory line in a plane perpendicular to the direction of feeding movement so that any point on the operative cutting surface of the tool follows an identical trajectory to progressively engage points on the operative surface of the tool with the workpiece. The relative forming movement is continued until the workpiece is formed to provide the desired complex surface. An electrolyte can be introduced between the tool and workpiece and an electric current supplied to the tool and workpiece for providing a combined electromechanical forming operation as well as supplying an abrasive suspension between the tool and workpiece.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
A method of forming a complex surface on a workpiece comprising the steps of supporting a workpiece and supporting a tool having a contour providing an operative cutting surface complementary to the desired complex surface to be formed for relative feeding movement toward and away from one another, subjecting said tool and workpiece to a relative feeding movement toward one another, simultaneously subjecting said tool and workpiece to a relative translational forming movement along closed trajectory lines in planes perpendicular to the direction of feeding movement so that any point on the operative cutting surface of said tool follows an identical trajectory to progressively engage points on the operative cutting surface of said tools with said workpiece, continuing said relative forming movement until said workpiece is formed to provide the desired complex surface, introducing an electrolyte between said tool and workpiece, supplying an electric current to said tool and workpiece to provide for a combined electromechanical forming operation and supplying an abrasive suspension between said tool and said workpiece.
Claim 2
Independent Claim
169 words
A method of forming a complex surface on a workpiece comprising the steps of supporting a workpiece and supporting a tool having a contour providing an operative cutting surface complementary to the desired complex surface to be formed for relative feeding movement toward and away from one another, subjecting said tool and workpiece to a relative feeding movement toward one another, simultaneously subjecting said tool and workpiece to a relative translational forming movement along closed trajectory lines in planes perpendicular to the direction of feeding movement so that any point on the operative cutting surface of said tool follows an identical trajectory to progressively engage points on the operative cutting surface of said tools with said workpiece, continuing said relative forming movement until said workpiece is formed to provide the desired complex surface, introducing an electrolyte between said tool and workpiece, supplying an electric current to said tool and workpiece to provide for a combined electromechanical forming operation and supplying an abrasive suspension between said tool and said workpiece.
